MAILlNG ENVELOP.

SPECIFICATION form'mg part of Letters Patent N0. 693,704, dated February18, 1902.

Application filed November 4, 1901. Serial No. 80,991. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT HABERSTROH, a citizen of the United States,and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inMailing-Envelops, of which the following is a specification. Y

This invention relates to improvements in mailingenvelops for thetransmission through the mails or otherwise of printed matters,circulars, merchandise, &c., which by their nature require that theenvelop shall be so constructed as to be readily opened for the purposeof examining its contents by the postal examiners and as readily closedafterward.

Although the invention is particularly well adapted as amailing-envelop, it may to equal advantage be used as a sealing devicefor wrappers, cartons, or packages, &c., that may require sealing andunsealing from time to time as circumstances may require.

The invention is carried out as follows, reference being had to theaccompanying drawings, wherein- Figure 1 is a rear view of the improvedenvelop shown open and unsealed. Fig. 2 is a longitudinal section on theline 2 2 shown in Fig. 1. Fig. 3 is a rear View of the improved envelopshown sealedand closed. Fig. 4; is a longitudinal section on the line 44shown in Fig. 3, and Fig. 5 is an interior view of the rear portion ofthe envelop.

Similar letters refer to similar parts Wherever they occur on thedifferent parts of the drawings.

In the drawings, A is the rear portion of an ordinary envelop,mailing-case, carton, &c., B, and B is the end flap thereon, adapted tobe closed over the rear portion A, as usual.

In practice I make on the rear portion A a perforation a, back of whichI secure to the interior of said portion A a cemented disk 0, preferablycoated with rubber cement or other suitable adhesive or sticky materialcapable of being stuck to another portion of the envelop, &c., bypressure. I also in practice make a perforation Z) on the end flap B,and on the outside of the latter I secure a cemented disk D, as shown,said disk being coated on its exposed portion with a coating of rubbercement or other suitable adhesive or sticky material. It will thus benoticed that the cemented portions of the disks 0 and D are exposedthrough the respective perforations a and b in the rear portion A of theenvelop and the interior portion of the end flap B.

To seal the envelop, carton, &c., it is only necessary to close the flapB and to press the exposed cemented portion of the disk D against thecemented portion of the disk 0 on the envelop portion A, by which theend flap B is caused to be heldin closed position relative to the rearportion of the envelop, 850.

If it is desired to open the envelop, all that is necessary to do is totake hold of the end portion of the flap B and raise it, causing thecemented portions of the disks 0 and D to separate, thus allowing thecontents of the envelop or package, 850., to be examined or removed.

The envelop, wrapper, carton, 860., may be repeatedly closed and openedfrom time to time in a manner as above described.

Although in practice I prefer to make perforations on the rear portionof the envelop and on the end flap and secure back of such portionscemented disks adapted to be stuck together, as above described, I Wishto state that I do not desire to confine myself to this exactconstruction, as I may, if so desired, dispense with such perforationsin the rear part of the envelop and the end flap and to attachpermanently to such parts cemented disks adapted to be stuck together inclosing the envelop or package, &c., and instead of attaching cementeddisks to such rear part of the envelop and to the end flap I may applycemented coatings to such respective parts adapted to be stuck togetherin closing the envelop, wrapper, package, &c., and to be readilydisconnected from each other in pulling the end flap. from the main bodyof the envelop, wrapper, &c., during the unsealing of the same.

What I wish to secure by Letters Patent and claim is- 1. An envelophaving its flap and its back provided with a non-hardening cement, fordetachably connecting the flap to the back.

2. The combination with the back and flap of an envelop, of a disk ofnon-hardening cement connected to tho flap, and a disk of non-hardeningcement connected to the back and adapted to engage'the disk of the flapfor detachably connecting the back and flap together.

3. An envelop provided with a flap having an opening, a back providedwith an openin g, a disk of non-hardening cement attached to theouterface of the flap and adapted to project through the opening, a diskof non- 10 hardening cement secured to the inner face of the back andadapted to project through the opening thereof, said disks of cementadapted to engage each other for detachably connecting the back and flaptogether.

In testimony whereof I have affixed my sig- 15 nature in presence of twowitnesses.
